BatteryRank review
A practical choice for phone-first carry when one cable-ready 30W output matters. When multiple ports are active, the bank’s full-system output is 24W rather than 30W per connected device.
Ratings below are manufacturer-claimed. Open a reading to see its source and check date; derived comparisons are identified separately.
Use and carrying fit
At 215g and 104 × 52.3 × 26mm, it combines a built-in USB-C cable with a separate USB-C port and USB-A. Anker specifies up to 30W from one USB-C output and cites charging an iPhone 14 to 50% in 30 minutes under its stated test conditions.
What changes the choice
The built-in USB-C cable or USB-C port can provide up to 30W individually. Anker lists 24W maximum total output when the bank shares power across outputs.
Its 10,000mAh capacity and 215g weight suit a compact carry. Anker rates the built-in cable or USB-C output at up to 30W individually, and total output at 24W across ports.
Before connecting devices
A port’s published maximum and the combined multi-port limit are separate ratings. A device can draw less than the bank’s maximum based on its own requirements and the negotiated charging profile.
The built-in USB-C cable and separate USB-C port each support up to 30W output. USB-A profiles include 10V⎓2.25A, equivalent to 22.5W; combined output is rated at 24W maximum.
Anker lists up to 30W input through either the built-in USB-C cable or the USB-C port.
